I am using ConnectApi.ChatterFeeds.getFeedItemsFromFeed to retrieve posts/Comments from Cases. But in feedItems,
by default only 3 comments are being displayed. I want to display all the comments for each post, using 'Show More' link, similar to out of the box salesforce feature. And i see that method ConnectApi.ChatterFeeds.getFeedItemsFromFeed was removed after version 31.0. Any help please ?

I recently got Data Loader 39 and was trying to update settings for updating nulls.  I can't seem to save the settings.  I scroll to bottom of settings the screen won't go to the end and can't save.  I'm I missing a step?
